Add CLI args and __main__ guard to final.py (part of #10)

[abhishekKokadwar]

Addresses the two remaining items from #10 (the IndexError is fixed separately in #11).

Bug

final.py hardcoded its input/output filenames (annotated_pos_sent.txt, output.vrt) and ran all its logic, including file I/O, at import time with no if __name__ == "__main__": guard. This is inconsistent with every other script in english/ and farsi/ (e.g. convert_to_xml.py uses argparse), breaks the batch pipeline usage described in Farsi_readme.md step 5 (which expects arbitrary file paths), and means the script can't be imported/unit-tested without side effects.

Fix

• Added argparse with -i/--input and -o/--output, using the previous hardcoded names as defaults so existing usage (python final.py with no args, from a directory containing annotated_pos_sent.txt) still works unchanged.
• Wrapped the processing logic in main(input_file, output_file) behind an if __name__ == "__main__": guard.

Note on overlap with #11

This branch was cut from main (not from #11's branch), so it also carries forward the len(parts) < 10 guard fix from #11 to keep the file consistent — otherwise this PR would silently regress that fix. If #11 merges first, this will need a trivial rebase (the only overlap is that one line + a whitespace nit); happy to do that once #11 is in.

Testing

Added farsi/test_final.py, which imports the module directly (safe now that there's no import-time I/O) and checks:

• the short-line regression case from Fix final.py IndexError on lines shorter than full CONLL-U (part of #10) #11 stays fixed
• main() correctly reads from and writes to caller-supplied paths

$ python test_final.py
all tests passed
$ python final.py --help
usage: final.py [-h] [-i INPUT] [-o OUTPUT]

Pull request overview

This PR updates the Farsi pipeline’s final.py script to behave like a proper CLI tool (rather than executing file I/O at import time), enabling batch/pipeline usage with arbitrary input/output paths and making the module safe to import for testing.

Changes:

• Added argparse (-i/--input, -o/--output) with defaults matching the prior hardcoded filenames.
• Moved processing and file I/O into main(input_file, output_file) and added an if __name__ == "__main__": guard.
• Added a self-check test script that imports final and verifies both the short-line regression and path-based I/O.

File	Description
farsi/final.py	Adds CLI args and __main__ guard; wraps processing in main() while preserving existing defaults.
farsi/test_final.py	Adds a self-check that imports final and validates short-line handling + custom input/output paths.
